T 0 all whom it may concern Be it known that 1, CHARLES "prisms, a citizen of the United States, residing at .LQW' Orleans, in the parish of Orleans and State of Louisiana, have invented. certain new and useful Improvements in Dumping-Cars, or" which the following is a specification, reference being had to the accompanying drawings. I

This in ention relates to railway cars, and particularly to dumping cars.

The primary object of this invention is the provision of a very easily operated, simply constructed dumping car, wherein the dumping operation may be eitected by air operated means controlled from engine of the train or may he edected in other Ways by the application of power thereto.

A further object of the invention is the provision of a dumping car having sides which, when unlocked, will yield outwardly for the discharge of material, and a floor formed in lateral sections. together with means whereby the floor sections may be raised at the middle so as to discharge mate-- rial laterally on both sides of the car beneath the sides ofthe car.

A further object of the invention is to pro" vide simple but effective means whereby the sides of a car may be held from any opening movement, these means being adapted to be shifted by hand into a released position and supported in this position.

A further object of the invention is to pro vide means whereby the operating meansof all the cars of a train may he connected to each other and operated from the engine of a train to secure a simultaneous discharge of material from all of the cars.

A further object of the invention is to so construct the car that it may he used either as a dumping car or as a flat car.

Other objects will appear in. the course of the following description.

My invention is illustrated in the accordpanying drmvings. wherein:

Figure l is a side elevation of a car constructed in accordance with my invention, the figure showing in clotted lines the position taken by one of thecar stakes when the side walls of the car are released; Fig. 2- is a top plan view of the car shown in Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. l but with the car door in its lowered position and the sides of the car in their locked and vertical position; Fig. 4 is a like View to Fig. 3 but showing the position taken by the car when the car is dumping and also showing the position taken by the sides at this time; Fig. 5 is a. longitudinal fragmentary section to the car shown in Figs. 1 and 2.

Referring to these drawings, 2 designates the framework forming the body of the car. This may be constructed in any suitable manner and is supported upon the trucks 3. I do not Wish to limit myself to any particular manner of; constructing the framework upon which the car body is supported. As illustrated, this frameworkconsists of transverse members 4 and longitudinal members or sills 5 and 6. Disposed at th ends of the car are the vertical posts 7 with the and boards or pieces 8 hinged at 9 to a supporting base 10 s. that these end boards or pieces 8 may be turned inwardly and downwardly as will be later stated. (arried upon these posts 7 and extending longitudinally along the car are the rods 11. These rods support the swinging sides 12. These sides may be made in sections but preferably each side extends the full length of the car.

The side members 12 are shown as supported upon the rods 11 by means of straps 13.

Each side piece 12 carries upon it a plurality of stakes 14: whereby the side may be locked in a vertical position. Each stake longitudinally slotted as at 15 and a headed pin 16 is disposed in the side piece 12 to project therefrom and passes through the slot 15. The lower end of each stake is reduced in cross sectional area as at 14 and is adapted to be inserted beneath a strap 17 attached to the beam or sill 6. Disposed adjacent the lower edge of the side piece 12 is an L'shaped strap 18 forming a socket or seat, open on one side, and disposed adjacent the upper edge of the piece 12 is an l..- shaped strap 19, which, however, has its open end directed opposite to the direction of the open end of the strap 18. From this construction it is obvious, as shown in Fl 1, that a stake 14 may he raised out of engageinent with the straps 17 and that when fully raised out of this engagement it may be rotated to the position shown in dotted lines in Fig. l, the upper end of the stake being received in a seat formed by an L- shaped strap 20 which is attached to the side wall 12. As many of these-stakes 14 may be is required to support the side walls ing rod23 which extends longitudinally of;

the car and is supported in any suitable manner in the posts 7 or upon the beams 6. Disposed beneath the floor sections 21 and 22 and normally extending horizontally in parallel relation to these floor sections are the floor lifters designated 24. These are approximately triangular in form, as seen mostclearly in Fig. 4, and each has out-- Wardly projecting trunnions 25 which extend-out through ball bearings 26 carried in the beams 6, these bearingsbeing protected by cover plates 27 which are attached'to the beams 6 in any suitable manner. The lifters 24 are therefore rotatable from a horizontal position to a vertical potion, and vice versa. Each of the lifters.

along each forward edge is cut away as at 28 and mounted in this cut-away margin is a roller 29 which is adapted to rotatably engage with "the under face of the cerre spending floor sections 21 and 22. It will now be obvious that when the% lifters 24 are raised from a horizontal to a vertical position, as shown in Fig. i, they will lift up upon the floor sections 21 and 22 and these floor sections will be raised. to the position shown in Fi 4 which will cause the material on that 001' section to be dumped laterally. The weight of the material tending-to slide of the floor sections will force the sides 12'open, swinging them outward upon the pivot rods 11 and the material contained {within the car will be discharged.

For the purpose of raising and lowering the lifters 24, i connect the lifters in one car to each other by means of chains or other flexible connections 30 so that all of the lifters will operate together.' "i dispose be: neath the car in any suitable position. the air cylinder 31 having therein e piston 32 and a. piston rod 33. This piston rod is operatively connected to the floor sections by means of a chain 34. which passes over a pulley 35. This pulley is preferably mounted upon ball bee-rings so that it will rotate as easily as possible. passes over the pulley and then to the free extremity of theiforemost wall of the lifters 3%, as illustrated in Fig. 5. It is ob vious that if the piston 32 be moved. to the right in Fig. .5 the chain 3% will be tightenec i and will cause the lifters to rotate to a verof the next wall of the he The chain tical position and lift the floor se o e 2-1 and 22 upward to-en inclined position, as illustrated in Fig. 4. The lifters are never raised to an absolutely vertical position but to a position nearly vertical so that when the pressure of air on the piston 32 is re leased the lifters will fall back or return to their normal position under the weight of the floor sections.

, The cylinder 31 is adaptedv to be con: cted by means of a pipe 360: 37 to air op rng means carried upon the engine, Preferably this pipe 36 extends to a compressed air reservoir on the engine and means are provided on the engine whereby the compressed air from this reservoir may be allowed to flow into the cylinder 31 to actuate the piston, It is obvious, however, that e reduction" in pressure might be made in one end of the cylinder. and atmospheric air be allowed to cause the operation of the piston. I do not wish therefore to limit myself to any particular means whereby air pressure-may be used'to operate the piston From the pipe 36 extends a pipe 37 whereby pressure may be carried on backto thepipe 36 It will be unand.

derstood, of course, that 37 are provided 3. h whereby they ma pipes of the next .ejl in order to prev]. lifters sis ope-rat sity of usin to the lif which e1}: 1 on t formed in the front o. e o

animals nzay be connected or to iicii the engine of a train may be connected, de sired. In order to secure e proper purchase upon. the lifters 2 whe .hey in their lowered or her positions I mount upon the fore ell end of the car and on a line beneath. the floor pelle The chain 34 willirest upon this pulley the lifters are in their lowered or he position and this will t pass upward and forward from t ity of the adjacent lifter so that pull upon the lifters is upwarz forward until the lifters have position where tb chitin from the pulley ii. necesseryfor the ehein passes or on 2. plane abcs'e the lifter If it be desired to l in l-" the suppo may be rein .L posts '3'. the supp rtir;

A! it ..g pro y with nuts at their ends which may be re moved to permit the removel of tee suph end rml s may 1e turned down not upon the iioor. There is thus provided a lint our having iioor but not having either ends or sides if it is desired to provide it flat our having ends, the end mei'nbers S are lifted in their vertical PiI-'-;ltl()li. These members 8 are looked in their vertical position by means of bolts 42 pnssirg through the posts 7 It will be seen that l have provided a very simple form of dumping ear and one in ivhieli the rontents of the our are readily dumped on each side of the track. After the contents of the car have i106! lun'iped the lifting members and the floor inll hook to their norm nyl position so that the ear is in the rum ition to receive a second loud of matei )ll the stakes are engaged n ith Lil ir s lei.

lt is to he understood that the pipes 36 and 37 are to he uncoupled. while the train running and these pipes are only to be coupled to ouch other when it desired to dump the ears. It will be obvious also that valves might be 'u'ovided which would per init of the dumping of eerinin oi" the ears of the train, lenxing the other cars of the train undninped. The car or train of cars can he eontroll d by an engine at either end and it the engi V i for compressing :iii' in he eylinder 3i or if the ear is placed upon a side track Without an engine, it is possible to unload the our either by attaching a team to the shackle 40 or by eonneeting the shackle to the engine itself. The team or the engine will then draw the lifting nieinhers into their operative position to dump the em.

The stakes ll are so arranged that they cannot he accidentally disengaged and these strikes will securely hold the sides 01 the or from any outward movement until they are released. After the contents of the our linre been dumped itn-t :in ma nutter to retu n the stakes to their originu. posit ion.
